Dear Jet-Pack (IPACS)
For the moment, I don't know how it happens, I might have done something wrong. I encountered it twice.
It will append posts to this thread whenever I know more about it.
From cold & dark, I set the MCDU, I'm almost sure that the TO DATA has entered F, S and O speeds. Takeoff as usually, the plane doesn't accelerate, the PDF doesn't show -F, -S or green dot speeds. Well, I checked MCDU pages and discovered that there was no managed speed set. No F, S and O speed set in landing page.
I'll tell you more, keep in touch.
Thank you for Aerofly FS 4 that runs so so so so so so greatly on the M1 Pro Mac.
